Technology Process of cis-{PPN}{RhBr₂(CO)2}

There total 5 articles about cis-{PPN}{RhBr₂(CO)2} which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield: 90.0%

rhodium(III) chloride trihydrate + bis(triphenylphosphine)iminium chloride (21050-13-5) → cis-{PPN}{RhBr2(CO)2} (125540-46-7)

Guidance literature:

With CO; NaBr; In ethanol; dissolution of RhCl3 in EtOH, filtn. into a round-bottomed flask under N2, passing a stream of CO slowly through soln., heating at 90°C with continued passage of CO (5 h), addn. of NaBr to the hot soln., addn. of PPNCl in abs. EtOH; filtn., addn. of distilled water to the filtrate, cooling in a CO atmosphere, pptn., filtn., washing with Et2O, drying in vacuo at 50°C, recrystn. by addn. of Et2O to a CHCl3-soln. of compd., elem. anal.;

Reference yield: 90.0%
